Try significantly reducing or eliminating that economizer low limit. It should not be needed unless there is humidification in the building. It appears that what is happening is not that "the VAV boxes are controlling OA", but the AHU OA damper is reducing OA% when the OAT is below 55F, so the MAT increases, so the AHU cooling coil uses more energy or CHW.
